a162f4e825 refactor(3p/nix/libexpr): Use std::string as qualified type
Replaces most uses of `string` with `std::string`.

This came up because I removed the "types.hh" import from
"symbol-table.hh", which percolated through a bunch of files where
`string` was suddenly no longer defined ... *sigh*

c395a48be2 fix(3p/nix): Compatibility with updated SymbolTable
The functions in SymbolTable have been renamed to match the Google
Style guide, and some debug-only functions have been removed.

97e85f94e5 refactor(3p/nix/libexpr): Use absl::node_hash_set in SymbolTable
This replaces the previous use of std::unordered_set with
absl::node_hash_set.

This type was chosen because the current implementation requires
pointer stability.

This does not yet touch the 'Attr' struct.

As a bonus, the implementation of the SymbolTable struct is now
consolidated into a single header/implementation file pair.

00017ace04 feat(3p/nix): Wrangle Meson/Nix/CMake into (temporary) submission
Meson is unable to use CMake in Nix to determine the internal
structure of the Abseil libraries.

This commit adds an explicit list of most of the Abseil targets that
are relevant (so far) and bundles them into a list that is linked
together.

9dfdf16a8d fix(3p/nix): Fix build of derivation if cmake is present
cmake automatically runs a configure hook which breaks the build,
since this isn't actually a cmake project. This hook is now disabled.

Additionally Abseil's sources are linked to an absolute derivation
path when the build launches, as opposed to the relative path used for
development builds.

d331d3a0b5 refactor(3p/nix): Apply clang-tidy's modernize-* fixes
This applies the modernization fixes listed here:

https://clang.llvm.org/extra/clang-tidy/checks/list.html

The 'modernize-use-trailing-return-type' fix was excluded due to my
personal preference (more specifically, I think the 'auto' keyword is
misleading in that position).

3908732181 style(3p/nix): Final act in the brace-wrapping saga
This last change set was generated by a full clang-tidy run (including
compilation):

    clang-tidy -p ~/projects/nix-build/ \
      -checks=-*,readability-braces-around-statements -fix src/*/*.cc

Actually running clang-tidy requires some massaging to make it play
nice with Nix + meson, I'll be adding a wrapper or something for that soon.

c6a31838cd fix(3p/nix/libexpr): Declare value union types explicitly
Previously these structs were declared anonymously inside of the -
anonymous - union. This is not actually supported by the C++ standard,
but is merely a compiler-specific extension.

Unfortunately untangling this required a forward-declaration of the
Value type.

b490742a51 style(3p/nix): Enforce braces around loops and conditionals
This change was generated with:

  fd -e cc -e hh | xargs -I{} clang-tidy {} -p ~/projects/nix-build/ \
    --checks='-*,readability-braces-around-statements' --fix \
    -fix-errors

Some manual fixes were applied because some convoluted unbraced
statements couldn't be untangled by clang-tidy.

This commit still includes invalid files, but I decided to clean them
up in a subsequent commit so that it becomes more obvious where
clang-tidy failed. Maybe this will allow for a bug-report to
clang-tidy.

f012012ef78234a6a4585321b67d7b7c92ebc266 by Laramie Leavitt <lar@google.com>:

Slight restructuring of absl/random/internal randen implementation.

Convert round-keys.inc into randen_round_keys.cc file.

Consistently use a 128-bit pointer type for internal method parameters. This allows simpler pointer arithmetic in C++ & permits removal of some constants and casts.

Remove some redundancy in comments & constexpr variables. Specifically, all references to Randen algorithm parameters use RandenTraits; duplication in RandenSlow removed.

bdbe6b5b29791dbc3816ada1828458b3010ff1e9 by Laramie Leavitt <lar@google.com>:

Change many distribution tests to use pcg_engine as a deterministic source of entropy.

It's reasonable to test that the BitGen itself has good entropy, however when testing the cross product of all random distributions x all the architecture variations x all submitted changes results in a large number of tests. In order to account for these failures while still using good entropy requires that our allowed sigma need to account for all of these independent tests.

Our current sigma values are too restrictive, and we see a lot of failures, so we have to either relax the sigma values or convert some of the statistical tests to use deterministic values.

This changelist does the latter.
